SEBA BOGERT, OF NEW YORK, N. Y.

FINGER-RING.

Specification of Letters Patent No. 25,172, dated August 23, 1859'.

T o all whom it mary concern:

Be it known that I, SEBA Booinrr, of the city, county, and State of New York, have' invented a new and useful Improvement in Finger-Rings; and I do hereby declare that the following is a full, clear, and eXact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a section of a ring constructed according to my invention x, ae, Fig. 2, indicates the plane of section. Fig. 2, is a side View of ditto. Fig. 3, a perspective view of ditto applied to the finger.

Similar letters of reference indicate corresponding parts in the several figures.

rlhe object of this invention is to obtain a finger ring capable of being extended or increased in diameter' beyond the size required for the portion of the finger on which it is worn so that the ring may be readily slipped over the joints of the finger in being taken ofi or adjusted thereon and atI the same time retained by asuitable catch in a distended state while being slipped or passed over the linger.

The invention consists in having the ring divided so that its ends may be drawn apart when necessary and its diameter increased and having a catch or fastening formed at the ends whereby the desired object is attained.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a linger ring which may be of gold or other material used for such purpose. The ring may be of any desired form, but the one represented in the drawings is designed for a stone, a, being the socket which receives it, the stone not being shown. The socket a, is at one end of the ring and a slot b, is made through its bottom, said slot having one or more jogs or notches c, which are shown `clearly in Figs. 2 and 3. To the other end of the ring a plate d, is attached, which plate slides underneath the bottom of the socket a, and is provided with a pin c, which is fitted in the slot b. The pin e, is allowed to move or work freely in the slot b, below the stone in the socket, the stone not being in contact with the pin.

The ring is distended by drawing apart its ends and it is retained in a distended state by having the pin c, fitted in one of the jogs or notches. The ring may then be readily shoved over the joints of the inger, and in adjusting the ring to the finger the pin c, by pressing the socket c, and plate d, toward each other in a direction transversely with slot Z), and consequently longitudinally with the jogs or notches c, will be shoved out of the jogs or notches and the ring will contract or return by its own elasticity to its original state and be snugly fitted on the linger. In taking the ring off from the finger, the ends are of course distended the pin c, being shoved in one of the jogs or notches c, in order to retain the ring in a distended state the same as when adjusting it o-n the finger.

I am aware that elastic o-r extension rings have been previously devised, and one patented by Friend and Seeber December 21, 1858, and reissued February 22, 1859, may be seen in which the ring is divided and its ends connected by a system of levers, known as the lazy tongs. This ring however is quite differently arranged from mine and it has no catch or fastening to keep it in a distended state depending on its elasticity only to allow it under pressure to pass over the joints of the finger.

l do not claim an extension ring formed by dividing the same so that its ends may be forced apart to increase its diameter depending` on its elasticity to enable it to contract, for such device has been previously used; but,

That I do claim as new and desire to secure by Letters Patent, is,

An extension or divided finger ring having its ends provided with a catch or fastening substantially as and for the purpose set forth.

slank sooner.
